OPTIONS The following options are available: -d device Specify the device type. To see a list of the sup ported devices, try -d help -r filename Read from eeprom and save to a file. -w filename Read from a file and write to eeprom. The addresses not specified in the input file will be filled with 00. -k filename Read from a file and write to eeprom. The addresses not specified in the input file will be kept with its previous values. (this mode is twice slower. It reads whole memory to know previous val ues, then write whole memory) -f XX Fills the whole eeprom with XX (xx is an hexadeci mal value) USAGE EXAMPLES eep24c -d 24c04 -r file.hex read eeprom, write to file.hex eep24c -d 24c04 -w file.hex read file.hex and write to eeprom. All the bytes not found in file.hex will be written as 00. eep24c -d 24c04 -k file.hex read file.hex and write to eeprom. All the bytes not found in file.hex will remain unchanged. eep24c -d 24c04 -f 7A fill eeprom with 7A (hexadecimal). INPUT AND OUTPUT FORMAT Input and output file format is Intel Hexadecimal Object File Format You can find this specification at ftp://download.intel.com/support/processors/ i960/devtools/INTELHEX.PDF Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline mark ers. Output files are generated with LF as a newline marker. DEVICE SPECIFIC If you are using Microchip 24*515, you must tie its pin A2 to VCC (needs a hardware modification, see device datasheet). SEE ALSO ihex2txt(1), txt2ihex(1).

First you get the original Intelhex file and use ihex2txt to convert it. Then you edit the text file and convert back to Intelhex using txt2ihex INTELHEX FORMAT Intel Hexadecimal Object File Format or simply Intelhex specification can be found at ftp://download.intel.com/support/processors/ i960/devtools/INTELHEX.PDF Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline mark ers. Output files are generated with LF as a newline marker. TEXT FORMAT The text format is composed by a line with values sepa rated with spaces. The first value is the initial address, the following values are the values. Example: 02B7 07 B9 70 7A 6E means that the content of address 02B7 is 07, the content of address 02B8 is B9, the content of address 02B9 is 70, ... SEE ALSO eep24c(1).

You can find the hardware schematics at the files: "eep.ps.gz" or if you prefer in "eep.jpg" Hardware connections: Build the hardware using the schematics and connect it to the parallel port of the computer. Common options: It uses by default LPT1 = 0x378. If you want to change it, edit the configuration file. Compiling/installing in GNU/Linux systems: make make install DESTDIR=/ edit the configuration file /etc/eep24c/eep24c.cfg Note: this program will access the parallel port hardware, it needs to be run by root or need to be root setuid. If you want only root to use it, than it is ready for use. If you want you can use the command: "chmod +s /usr/bin/eep24c" to enable all users. To uninstall try: make uninstall DESTDIR=/ Compiling/installing in DOS systems: edit common.h and read the instructions Compile with your prefered compiler. Choose "compact" memory model. Put the .exe files and also eep24c.cfg in C:\eep24c\ Modify eep24.cfg if needed. eep24c-0.1.2/common.h0000644000175000017500000000225110265023462013675 0ustar pznpzn00000000000000/* Copyright (C) 2002 Pedro Zorzenon Neto This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

To see a list of the supported devices, try .B \-d help .TP .B \-r filename Read from eeprom and save to a file. .TP .B \-w filename Read from a file and write to eeprom. The addresses not specified in the input file will be filled with 00. .TP .B \-k filename Read from a file and write to eeprom. The addresses not specified in the input file will be kept with its previous values. (this mode is twice slower. It reads whole memory to know previous values, then write whole memory) .TP .B \-f XX Fills the whole eeprom with XX (XX is an hexadecimal value) .TP .B n Can be used to multiply clock time. If you have a long cable, you may use this option. Example: \-r5 will read eeprom 5 times slower (pulse width will be standard value multiplied by 5). Valid range for n is from 1 to 50. Default value is 1. .SH USAGE EXAMPLES .TP .B eep24c -d 24c04 -r file.hex read eeprom, write to file.hex .TP .B eep24c -d 24c04 -r3 file.hex read eeprom, write to file.hex, 3 times slower. .TP .B eep24c -d 24c04 -w file.hex read file.hex and write to eeprom. All the bytes not found in file.hex will be written as 00. .TP .B eep24c -d 24c04 -k file.hex read file.hex and write to eeprom. All the bytes not found in file.hex will remain unchanged. .TP .B eep24c -d 24c04 -f 7A fill eeprom with 7A (hexadecimal). .SH INPUT AND OUTPUT FORMAT Input and output file format is .B Intel Hexadecimal Object File Format .br You can find this specification at .br ftp://download.intel.com/support/processors/ .br i960/devtools/INTELHEX.PDF .br Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline markers. Output files are generated with LF as a newline marker. .SH DEVICE SPECIFIC If you are using Microchip 24*515, you must tie its pin A2 to VCC (needs a hardware modification, see device datasheet). .SH SEE ALSO .BR ihex2txt (1), .BR txt2ihex (1). .br .SH AUTHOR This manual page was written by Pedro Zorzenon Neto . eep24c-0.1.2/eep24c.c0000644000175000017500000001510610265023516013465 0ustar pznpzn00000000000000/* Copyright (C) 2002 Pedro Zorzenon Neto This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

First you get the original Intelhex file and use .B ihex2txt to convert it. Then you edit the text file and convert back to Intelhex using .B txt2ihex .SH INTELHEX FORMAT .B Intel Hexadecimal Object File Format or simply Intelhex specification can be found at .br ftp://download.intel.com/support/processors/ .br i960/devtools/INTELHEX.PDF .br Record types 00 and 01 are implemented in this version. In input lines, LF and CR+LF are accepted as newline markers. Output files are generated with LF as a newline marker. .SH TEXT FORMAT The text format is composed by a line with values separated with spaces. The first value is the initial address, the following values are the values. .br Example: .B 02B7 07 B9 70 7A 6E .br means that the content of address 02B7 is 07, the content of address 02B8 is B9, the content of address 02B9 is 70, ... .SH SEE ALSO .BR eep24c (1). .br .SH AUTHOR This manual page was written by Pedro Zorzenon Neto . eep24c-0.1.2/ihex2txt.c0000644000175000017500000000424210265023472014162 0ustar pznpzn00000000000000/* Copyright (C) 2002 Pedro Zorzenon Neto This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
